Suggestions for dealing with a partner (24M) who tends to be consistently negative. I’m [23F].

The negativity began during our college dating days, where he would frequently vent about various frustrations. He is quite expressive and tends to voice (often rant) his emotions, while I tend to keep things to myself and focus on the positives. This was definitely a new experience for me. Each day brought a new concern—or sometimes the same issue on repeat. Whether it was annoying professors, traffic jams, or problems with friends, he always seemed to find something to be upset about. Our discussions often escalated into arguments, with me feeling frustrated by his constant negativity and trying to offer advice to help him move past it. Unfortunately, this would typically end with him upset that I was playing "devil's advocate" instead of supporting him. He often reacted intensely to issues that seemed trivial or not as serious as he perceived (as he tends to overthink). I struggled to agree with his viewpoint, and it eventually reached a point where I felt I had to concede to his opinions—even when I knew he was mistaken—just to avoid further conflict. He frequently reassured me that once we graduated, these minor annoyances would disappear and he would be much happier. Fast forward to after graduation, and he is dissatisfied with his job and daily struggles with traffic. Living together means that I’m confronted with his complaints every day. I even started avoiding his calls after work, as listening to him rant about his boss and traffic during the drive home really affected my mood. He now attributes his unhappiness to the job, insisting that everything will improve once he finds a new position. However, I’m starting to worry that no matter what job he ends up in, there will always be something else bothering him. He has this mindset that he can't catch a break and that the world is against him. We’ve had numerous discussions about this, but I’m uncertain how to bring it up without risking offense or him deflecting it as an issue specific to his current job and commute. How can I express my concerns without it escalating into a conflict or making him feel attacked?
